North Seymour Island is just north of Baltra and was formed through a series of sporadic uplifts. It took about a million years for the island to reach its current level. Now above the sea, the layers of lava that originally erupted underwater have created a low-lying island packed with wildlife. The island is home to the largest nesting colony of frigatebirds in the Galapagos along with blue-footed boobies, finches, land iguanas, marine iguanas, and sea lions. A hike along shore and into the island’s interior brings you up close and personal to just about everything the island has to offer. You can also choose to go on a short Zodiac ride along the coast to search for fur seals, sea lions, and red-billed tropic birds. And for the more adventurous and experienced, jump in for a deep-water snorkel.
